@john-rocky this is good!

We want to keep models out of the codebase though (as in main branch), since otherwise subsequent changes will make the git chain very long and heavy. Can you remove the YOLOv8m CoreML model from this PR?

[john-rocky]

I removed Yolov8m coreml model from code.
The app download it.
